Google has allowed in its search engine tweets for smartphones and tablets users.

"Starting Tuesday, we are bringing Tweets to Google Search on mobile devices. So now when you're searching on the Google app or any browser on your phone or tablet, you can find real-time content from Twitter right in the search results," said Google in its blog post.

Twitter and Google inked the deal in February to give Google access to the half billion daily tweets and show them in search results.

To begin with, the service is available on Google.com in English in the Google app (on Android and iOS) and on mobile browsers, rolling out gradually.

"We are working on bringing it to more languages and to desktop, so stay tuned," the blog post read.

Ardan Arac, senior product manager for Google, wrote: "It is a great way to get real-time info when something is happening. And it is another way for organisations and people on Twitter to reach a global audience at the most relevant moments."
